A few weeks ago, there was a posting on CR4 on some funny answers to math exams. One was a "find x" 3-4-5 right triangle, with a "there it is" answer. Another had an expand (a + b)^n. I have been using the CR4 search tool for an hour trying to find that thread with a dozen keywords that I can recall and darned if I can find it. Can anybody point me to it?
Thanks very much.
